Cloud services offer doctors and data scientists access to medical data from multiple
locations using different devices (laptops, desktops, tablets, smartphones, etc.). Therefore …

One of the fastest-growing industries in recent years has been e-Healthcare. Many
cyberattacks and threats against patient confidentiality exist in electronic health records …

Nowadays, digital medical images have become an essential source for the grand success
of e-health technology. At the same time, the massive storage also plays a vital role. One of …

This paper presents a quantum image steganography algorithm based on HSI color space
embedding technique. To increase the security of sensitive information, a three-dimensional …

Recently, many existing image encryption schemes suffer from security vulnerabilities due to
system key leakage. In response to this issue, this paper proposes a novel asymmetric …

In the domain of Internet of Things (IoT) applications, quantum computers offer the promise
of addressing complex computational issues that traditional cryptographic methods find …

These days, spectrum insufficiency is the most common issue. If the number of smartphone
users who access the radio spectrum grows, the radio spectrum becomes increasingly …

The security of images is closely related to the protection of information privacy. We
proposed a novel 5D memory resistive chaotic system (5D-MRCS), which exhibits good …

The local dynamical behaviors of a four-dimensional hyperchaotic Lorenz system, including
stability and bifurcations, are investigated in this paper by analytical and numerical methods …

A quantum image steganography algorithm based on edge detection is proposed. Firstly, a
new fractal chaotic system with good chaotic properties is proposed to improve the security …
